The analog part of a current-mode CMOS 5-b bidirectional digital/analog (D/A) converter for digital audio with 115-dB dynamic range and -90-dB distortion at 128-times oversampling is presented. The application of a multibit noise shaping approach combined with a sign-magnitude decoding in an oversampled D/A converter not only increases the dynamic range of the converter but also reduces the intermodulation sensitivity. A dynamic self-calibration technique is used to obtain the required relative accuracy and absolute linearity of the current sources. No laser or external trimming techniques are required.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
